Is there a map for a pinto 2.5 l engine available? As this is the smallest engine on the Holley spec sheet. 1/2 shouldn’t make a difference. See how they deal with throttling down the carb. There must be a way as they claim you could run up to 7 liters.

It is not a fine spray, but rather a squirt.

On a throttle body injector, the fuel shears to a fine droplet as it passes the throttle plate when at idle.

Read the 1987 info from GM that discusses issues when folks think it's a good idea to speed up the idle by messing with the throttle opening instead of being smart enough to burn a new chip with revised idle speed table (used to do chip mods for GMs).  Crank the throttle plate open and the idle goes to hell.  The same goes for drilling holes in the throttle plate.

Fix the idle air valve follower setting to avoid stalls, that's what it is for.

I have the IAC set correctly, hence the throttle plate is within specs.

I am messing with the iac hold position.

I have booked a dyno tune on the 12th. Not because I think it is a tuning issue, rather just to get the best out of what I have.

Is your manifold still heated? Could that be an issue with your fuel puddling?

 

 I know it’s no solace but we are all rooting for you!

I also read on the Holley forum that a 1" carb spacer may help to get better fuel mixture

I am going to “peanut” the manifold which should give it at least a clear inch including the adapter plate.

That was a good link they found- sounds just like this problem.  (Although I think the guy should really just nut up and buy a Windows laptop- sometimes you just need it...)

The problem is, no-matter how many nuts you up, and no-matter how big or small they are, they fall off the moment you press the power button on said windows computer.

I never said it was a good solution; sometimes you just need one...

 

Probably say that about a few things, huh?

Cap off the nipple for the brake booster at the intake, looks like a lot of people think it maybe that.
